TLDR
- Being under investigation means the police have a report with your name on it and the prosecutor has not yet decided whether to file a charge.
- Silence from the detective does not mean the case died, because most Arizona felony reports stay open for seven years and most misdemeanor reports for one year.
- You do not have to talk to the detective, and the safest first move is a lawyer who takes over every contact with the police and the charging unit.
- A written defense presentation delivered before the charging decision is your one chance to end the case with no filing, no arrest and no court date.
What “under investigation” means in Arizona
Someone made a report. A patrol officer took a statement, a detective picked up the file, and your name is in it as the suspect. No judge has seen it. No charging document exists. You have not been booked, or you were booked and released with no court date on the paperwork. That gap is the pre-file stage, and it is the least understood part of an Arizona criminal case.
The signs are familiar. A business card in the door frame. A voicemail from a detective who needs “your side of the story.” A call from a Department of Child Safety caseworker. A search warrant served on your phone or your home. A forensic interview scheduled for your child. An ex who tells you the police came by asking questions.
Each of these means the investigation is active. None of them means a charge is coming. The detective’s job is to build a file the prosecutor will accept. Your interview, your consent to a search and your texts to the other party are the fastest way to fill that file. Read why it is so hard to say no to the police before the next call comes.
How the police and the prosecutor decide whether to charge you
Arizona splits the decision in two. The police investigate and write a report with a recommended charge. The prosecutor decides whether to file it. City prosecutors review misdemeanors. The county attorney’s office reviews felonies. In Maricopa County a charging attorney reads the report and picks one of three paths.
File. The prosecutor files a complaint or asks a grand jury for an indictment. You get a summons in the mail with a court date, or a warrant issues and you are arrested. Felony cases land in the Maricopa County Superior Court criminal department, often through an early disposition court for lower-level offenses. Misdemeanors go to a city or justice court.
Turn down. The prosecutor declines to file. Sometimes you get a letter. More often nobody tells you anything, and the report sits in a closed file.
Further. The prosecutor sends the report back to the detective with a list of what is missing. A witness interview. A medical record. A second try at getting you to talk. A furthered case is still open and often comes back months later with the gaps filled.
Being under investigation but not charged puts you somewhere on that path without knowing where. Nobody has to tell you the report went up or that it was declined. You learn about a filing when the summons arrives, when a warrant surfaces during a traffic stop, or when a lawyer checks for you. If you are handling this alone, look up your name in the Arizona case search every few weeks.
How long the prosecutor has to file charges
The waiting is the hard part. People assume a few quiet months means the case died. In Arizona it usually means the report is in a queue.
As of 2026, the filing windows work this way. Most felonies carry seven years from the date of the offense. Most misdemeanors carry one year. Petty offenses carry six months. Homicide, several serious sex offenses and a short list of others carry no time limit. The clock stops while you live outside Arizona, so moving away does not run out the window.
Misdemeanor decisions come faster because the one-year window forces the issue. A report recommending misdemeanor assault or disorderly conduct often gets a decision within a few months. Felony charging units in the larger counties commonly take three to nine months on a routine report, longer on cases with lab work, a forensic interview or a phone extraction.
The window is the prosecutor’s deadline, not your waiting period. The charging decision is the only moment a defense presentation reaches a prosecutor who has not yet committed to a position. Our Phoenix criminal defense lawyers treat the pre-file stage as the best point in the case to win it, because a turndown ends everything with no public record of a charge.
The Law Behind This
| Charge or relief | What the law says | What it means for you |
|---|---|---|
| Misdemeanor assault | A.R.S. § 13-1203 makes causing injury a class 1 or 2 misdemeanor and makes causing fear of injury or an insulting touch a class 3 misdemeanor | Most bar fights, family arguments and neighbor disputes under investigation land here, with a one-year filing window |
| Disorderly conduct | A.R.S. § 13-2904 covers fighting, unreasonable noise, provoking language and reckless handling of a weapon, a class 1 misdemeanor except the weapon count, a class 6 felony | The usual companion count on an assault report, filed when the assault proof is thin |
| Domestic violence label | A.R.S. § 13-3601 attaches the domestic violence designation to an underlying charge between spouses, partners, roommates and relatives, and allows arrest on probable cause without a warrant | A label, not a separate crime, that brings mandatory treatment classes on conviction and firearm consequences |
| Misdemeanor jail exposure | A.R.S. § 13-707 caps jail at six months for a class 1, four months for a class 2 and thirty days for a class 3 misdemeanor, with a bump up one class for a repeat within two years | The ceiling if a misdemeanor report turns into a filed case |
| First felony prison exposure | A.R.S. § 13-702 sets first-offense prison ranges from four months on a class 6 felony up to twelve and a half years on a class 2 felony | Why a felony investigation, even a quiet one, deserves a lawyer before the charging decision |
What a pre-file defense attorney does before a charge exists
The work starts the day you call. A lawyer sends a letter of representation to the detective and to the charging unit. From that point every request for an interview, a polygraph, a DNA swab or a phone passcode goes to the lawyer, and the answer is usually no. The letter also tells the prosecutor a defense exists, which changes how the report gets read.
Then the lawyer builds the other side of the file. The detective’s report holds what the accuser said and what the officer saw. It rarely holds your text thread showing the accuser invited you over, the doorbell camera video from your porch, the receipt that places you across town, or the three witnesses who saw who swung first. A pre-file lawyer collects those items while they still exist, interviews witnesses before memories harden, and preserves the evidence in a form the prosecutor will trust.
The finished product is a written presentation to the charging attorney. It lays out what happened in your case, attaches the evidence, and explains why the report does not support a charge or why a filing would lose at trial. In one felony assault investigation, that packet, paired with a refusal to give a statement, ended in a turndown with no prosecution. In a felony abuse and endangerment investigation, the case closed for lack of probable cause after the forensic interview came back.
On a felony report, where first-offense prison ranges run from months to more than a decade, the lawyer also watches the dockets and warrant lists. You learn about a complaint the day it is filed, a self-surrender or summons keeps you out of a jail booking, and a release plan is ready for the first court appearance. Clients get recorded video updates at each step.
Pre-file representation at Future First Criminal Law runs on a flat fee that covers the investigation stage, with payment plans available. The numbers are published on our pricing page. Zachary Divelbiss founded the firm, which holds 250+ five-star Google reviews, and the trial record behind those reviews is why a charging attorney reads our letters closely.
What to do this week if a detective has called
Do not call the detective back to explain. Take the name and number, say a lawyer will be in touch, and stop. You hold the right to remain silent before any charge is filed, and using it is not evidence of anything.
Do not consent to a search of your phone, your car or your home. Ask for the warrant. If a warrant exists, step aside and say nothing.
Do not contact the person who made the report. Not to apologize, not to ask what they said, not through a friend. A text to the accuser turns an assault investigation into a witness tampering investigation, and it hands the detective a fresh statement.
Do not delete anything. Deleting texts or photos after you learn of an investigation is its own crime, and it reads as guilt to a jury. Preserve instead. Screenshot the thread, save the videos, and write down who was there and what they saw, dated today.
Stay off social media about it. Every post is a statement the prosecutor gets to use, and none of them help. Then call a lawyer. The earlier the letter of representation arrives, the fewer statements exist for the prosecutor to work with.

Frequently Asked Questions
How do I know if I am under investigation in Arizona?
The clearest sign is direct contact from a detective by phone, voicemail, business card or letter. Other signs include a search warrant, a Department of Child Safety visit, a forensic interview of your child, or friends telling you the police asked about you. No public database lists open investigations, so a lawyer’s inquiry to the agency is often the only way to confirm one.
Should I talk to the detective to clear things up?
No. The detective already has the accuser’s version and is asking for yours to compare the two and find the contradictions. An innocent explanation given without the report in front of you becomes a “changed story” once one small detail is off, and that becomes the prosecutor’s best evidence. Give the detective your lawyer’s name and let the lawyer handle the conversation.
Does no charge after six months mean the case is over?
No. Misdemeanor reports stay open for one year and most felony reports for seven, and Maricopa County felony charging units often take longer than six months on a routine file. The case is over when the prosecutor issues a written turndown or the filing window closes. Until then, treat it as active.
Will I be arrested at work if charges are filed?
It depends on how the prosecutor files. Most misdemeanor and many felony filings start with a summons mailed to your last known address, which gives you a court date rather than handcuffs. A warrant is more likely on serious felony cases or when the police believe you are a flight risk, and a lawyer watching the docket arranges a self-surrender before a patrol officer finds you.
Should I contact the person who accused me?
No, and that includes messages through friends or family. Any contact after you learn of the investigation risks a witness tampering or harassment allegation, which is often easier to prove than the original report. It also gives the accuser a reason to request an order of protection, and violating one of those is a separate charge.
Does an investigation show up on a background check?
An investigation with no arrest generates no court record, so standard employment checks show nothing. An arrest with no charge filed does create a booking record with the arresting agency and the Department of Public Safety, and some checks surface it. Sealing an arrest record with no conviction is a separate application, and Arizona Record Removal handles that work after the case closes.
Do I need a lawyer if I did nothing wrong?
Yes, because the charging attorney never hears your version unless someone puts it in front of them in a form they trust. Innocent people get charged when the only account in the file is the accuser’s. A pre-file lawyer builds the record showing what happened in your case before the prosecutor commits to a position.
What does “released pending further investigation” mean?
It means you were arrested or detained, the officer did not have enough to submit charges on the spot, and the report went to a detective for follow-up. No court date exists yet, and one arrives only if the prosecutor files. This is one of the most common pre-file situations in Arizona, and it is the point at which a lawyer’s letter has the most effect.
